S. Praveen Kumar, S. Sathiyamurthi, P. Poonkodi, T. Muthukumararaja & V. Prabudoss · Journal of Advances in Biology & Biotechnology · 2026

Boron (B) dynamics in calcareous soils are strongly influenced by soil chemical properties, which affect its availability and transformation. A factorial experiment was conducted to evaluate the effect of boron sources (borax and boric acid) and application level (0, 2.5, 5, and...

Influence of Zinc Sources and Levels on Zinc Fraction Distribution in Calcareous Soil under Groundnut (Arachis hypogaea L.)

S. Praveen Kumar, S. Sathiyamurthi, P. Poonkodi, T. Muthukumararaja & V. Prabudoss · Journal of Advances in Biology & Biotechnology · 2026

Zinc deficiency is a major constraint to crop production in calcareous soils due to high soil pH and calcium carbonate–induced zinc fixation, which reduces zinc availability to plants. The present study was conducted to evaluate the effects of different zinc sources and applicati...
